Al Ahly took control of Group A after beating rivals Zamalek 4-2 to move three points clear in their pursuit of a place in the CAF Champions League semi-finals.
The result ensures that the African Champions are in poll position to secure a place in the semi-finals ahead of their final group game against Orlando Pirates in South Africa.
The Sea Robbers lost 1-0 to AC Leopards on Saturday, which opened up the group, and the South Africans will now have to hope that Zamalek do them a favour against Leopards in their final game while they will need to secure points against Al Ahly.
Spectators enjoyed a thrilling Egyptian derby which saw Zamalek take the lead when Omar Gaber fired home before Walid Soliman smashed in the equaliser.
Al Ahly were ahead in the 15th minute when Ahmed Abdel-Zaher nodded in Ahmed Fathi's cross before Mohammed Abou-Treika scored after the break to make it 3-1.
Ahmed Fathi opened the gap even further and although Ahmed Hassan pulled a goal back for Zamalek, it was too little too late.
In the second game of the day, Coton Sport de Garoua failed to close the gap on Esperance as they played out a goalless draw away to Sewe Sport. It did not matter much as Sewe Sport and Recreativo Libolo cannot catch Coton or Esperance in Group B.
